ZERO POINT RESET
ZERO POINT RESET : DescriptionINFOID:0000000009460737
Zero point reset is an initializing procedure for the OCS (weight) sensors that must be performed using CON-
SULT when removing and installing passenger seat or servic ing the OCS system. If zero point reset is not per-
formed, the initialization is incomplete and OCS may not operate normally.
NOTE:
• When reinstalling the passenger seat, the initial value for the OCS sensors may change, and the OCS may
not operate normally.
• When zero point reset is performed after removal and installation of passenger seat, CONSULT displays "complete".
ZERO POINT RESET : Spec ial Repair RequirementINFOID:0000000009460738
1.PERFORM ZERO POINT RESET
1. Perform preliminary checks: NOTE:
• Level the vehicle
• Minimize vibrations near the vehicle
• Remove any objects on passenger seat
• Do not touch the vehicle during zero point reset
2. Select START on ZERO POINT RESET from , WORK SUPPORT of “OCCUPANT DETECTION”.
3. “Zero point reset” starts.
>> GO TO 2.
2.CONFIRM RESET
1. Check that "Complete" is displayed on “Zero point reset status”.
CAUTION:
• “Complete” may be displayed if the seat has been reinstalled, or “zero point reset” has already been
performed.
• "Incomplete” may be displayed if a new seat is installed.
• Air bag warning lamp flashes in user mode if zero point reset is "incomplete".
Is zero point reset status "complete"?
YES >> Print out “ZERO POINT RESET CURRENT STATUS” screen. Inspection end.
